Sound quality description
In this review, I use the standard eartips size L and drive it with the FiiO M15.
The EPZ K1 has a neutral-conscious W-shaped sound signature.
Please see here for detailed reviews on sound quality.
Lows / Bass
The EPZ K1's low frequency range is fairly linear and deep, but it does not reach the really deep heavy bass.
The bass drum sound is moderately heavy and has a reasonable sense of power, but the rumble is a bit weak and shallow. The sense of realism is a bit lacking.
The electric bass is not so bad in terms of tightness, but lacks a bit in spaciousness. Blackness may also be a bit lacking.
The bass is relatively flat and well balanced with the midrange, and those who are used to the low frequency range of monitor speakers will like it a lot. However, it is a bit lacking for those who like low frequencies.
The midrange of the EPZ K1 is tuned fairly close to neutral; the K1 is a fairly inexpensive 1BA+1DD hybrid, but it is both clear and surprisingly high-resolution for its price.
The midrange is a bit more depth-enhanced, and the soundstage allows more room around vocals. The left and right sides will feel a bit wider. The midrange is less dense and the area around vocals is clean and comfortable to listen to, but localization is a bit unstable, as violins and woodwinds tend not to stand upright and guitar edges tend to sound pulled back.
Even the sense of construction is lacking, and the midrange is softly contoured and pleasant to the ear for listening. The listening experience is comfortable and immersive, and there is plenty of detail, but the sense of separation is a bit weak. Peaks are also a bit prominent in the highs, which tend to be a bit sharp, and tend to sound crisp and dry.
Highs / Treble
The EPZ K1 should have a balanced armature driver handling the high frequencies, but extension is standard or slightly better, with good extension. It is tuned for definition and excels in detail and subtlety.
High frequencies are not lacking in detail, with ample luminance. Dynamism tends to be quite pronounced, and woodwinds and strings sound wavering, so the sense of localization is not stable, but it is lively and quite interesting.
The airiness is adequate, the highs are exhilarating, and the cymbal crash has good spread. The highs are unreliable as monitors due to localization issues, but are an excellent adjustment for listening applications.
Sound quality general comment
The EPZ K1 are IEMs with resolution and high transparency on par with ultra-high end. The midrange is also highly accurate, and the overall balance is tuned close to that of monitor speakers. However, the emphasis on staging and dynamism makes it difficult to get a sense of localization, making the sound more suitable for listening than for monitoring.
